**Master's Thesis - Numerical Simulation of Instabilities in Water Bath Vaporizers (M/F/d)**

Pullach nearby Munich, Germany | req17736

**What you will enjoy doing**
- We are currently looking for a highly motivated student for an exciting and challenging project in the field of two-phase flow instabilities.
- Water bath vaporizers (WBV) are used in cryogenic and petrochemical plants to vaporize liquefied gases such as oxygen, nitrogen, argon, ethylene or propylene by using hot water. They are usually part of the plant back-up system which comes into operation when there is shortage of product from the main plant.
- The evaporation of cryogenic liquids inside WBV involves a complex interplay of several different types of boiling mechanisms, prone to two-phase flow instabilities. These can reach large amplitudes within a short time, which is critical not just from an operational but also safety point of view.

In this Master Thesis you will
- Analyze characteristics of two-phase flow instabilities in WBV
- Use in-house developed numerical simulation model to solve mass, momentum and energy balances in 1D focused on identifying main influence parameters for equipment design
- Conduct studies on influence parameters to derive basic guidelines for equipment design
- Evaluate potential countermeasures based on their effectiveness and cost impact
- Receive supervision from experts in Equipment Process Design and Computational Mechanics department

**What makes you great**
- You are a student of process engineering, chemical engineering or mechanical engineering or similar with very good study achievements
- You have advanced knowledge in heat and mass transfer, fluid mechanics and thermodynamics
- Experience in numerical modeling and simulation as well as very good programming skills in Matlab, Python, C/C++, or similar is a must
- Knowledge in simulating multi-phase flows with heat and mass transfer using CFD (OpenFoam and/or Ansys Fluent) is beneficial
- You have an interdisciplinary thinking, commitment and ability to work independently
